Optics (2014)
Book Chapter

This chapter introduces the fundamental principles of geometrical and physical optics, providing a foundational understanding essential for further study in physics and engineering. Beginning with the nature and propagation of light, ray types, the c... Read More about Optics.

Momentum (2014)
Book Chapter

This chapter introduces the concept of momentum, a fundamental quantity in classical mechanics. Beginning with linear momentum and its relationship to Newton’s laws of motion, the chapter defines momentum as the product of mass and velocity and explo... Read More about Momentum.

Time-dependent thermo-creep analysis of rotating FGM thick-walled cylindrical pressure vessels under heat flux (2014)
Journal Article

In the present study, time-dependent thermoelastic creep response for isotropic rotating thick-walled cylindrical pressure vessels made of functionally graded material (FGM) has been investigated, taking into account the creep behavior of the FGM pre... Read More about Time-dependent thermo-creep analysis of rotating FGM thick-walled cylindrical pressure vessels under heat flux.

Face recognition via edge-based Gabor feature representation for plastic surgery-altered images (2014)
Journal Article

Plastic surgery procedures on the face introduce skin texture variations between images of the same person (intra-subject), thereby making the task of face recognition more difficult than in normal scenario. Usually, in contemporary face recognition... Read More about Face recognition via edge-based Gabor feature representation for plastic surgery-altered images.

Treatment of Automotive Gas Oil (AGO)-contaminated water using activated carbon from Indian bamboo (2014)
Journal Article

This study investigated the ability of activated carbon extracted from Nigerian-grown Indian bamboo, to absorb hydrocarbon from automotive gas oil -contaminated water. The water was polluted in the ratio of 3:1 (that is, 3parts of water to 1part of a...

Investigation of ground water quality during the dry season in Rivers State, Nigeria: A case study of Port Harcourt Metropolis (2014)
Journal Article

This research is to investigate the quality of ground water in boreholes and hand-dug wells during the dry season in six locations in Port Harcourt metropolis of Rivers State. The locations are Rumuola, D-line and Trans-Amadi, which use borehole whil...

Effect of heat flux on creep stresses of thick-walled cylindrical pressure vessels (2014)
Journal Article

Assuming that the thermo-creep response of the material is governed by Norton's law, an analytical solution is presented for the calculation of time-dependent creep stresses and displacements of homogeneous thick-walled cylindrical pressure vessels.... Read More about Effect of heat flux on creep stresses of thick-walled cylindrical pressure vessels.

The effect of septic tank locations on borehole water quality in Port Harcourt, Nigeria (2014)
Journal Article

The effect of septic tank locations on borehole water quality in five locations in Port Harcourt metropolis of Rivers State, Nigeria, was investigated. The locations were Miles I and III, Old GRA, Rukpokwu and Ada George. Three boreholes and septic t...

Application of a conditional approach for multivariate extreme values to flood risk (2014)
Presentation / Conference Contribution

Flood risk is a function of probability and consequence. Flooding events can arise from different sources, pluvial, fluvial, groundwater and coastal flooding. Sometimes flooding at a specific location arises from a single source in isolation. Often h... Read More about Application of a conditional approach for multivariate extreme values to flood risk.

A novel cutting strategy for measuring two components of residual stresses using slitting method (2014)
Journal Article

An exact knowledge of residual stresses that exist within the engineering components is essential to maintain the structural integrity. All mechanical strain relief (MSR) techniques to measure residual stresses rely on removing a section of material...
